هدف از مقالة حاضر، تدوین یک قانون هدایتی صریح برای مسائلی با ماهیت تغییر یا اصلاح مسیر حرکت ماژول‌های زیرمداری است. روش مورد استفاده، مبتنی بر حل مسئلة لامبرت بوده و از این رو، دو روش کارآمد در این حوزه معرفی شده و مورد ارزیابی و مقایسه قرار خواهد گرفت. بر این اساس یک سناریوی هدایت معرفی شده و در مسئله تحت بررسی به‌کار گرفته می‌شود. متأسفانه تمامی روش‌های حل مسئله لامبرت از فرض میدان گرانش نقطه...
Previous work has demonstrated that a subset of macrophages expresses a folate receptor (FR) that can mediate internalization of folate-linked molecules, including imaging and therapeutic agents. To characterize this subset, macrophages were collected from peritoneal cavities of mice injected with saline, thioglycolate, zymosan, heat-killed or live bacteria, and cell-surface markers that coexpr...
The spacetime ontology is considered in General Relativity (GR) in view of the choice of a frame of reference (FR). Various approaches to a description of the FR, such as coordinate systems, monads and tetrads are reviewed. It is shown that any of the existing FR definitions require a preexisting background spacetime, which, if defined independently of the FR, renders the spacetime absolute in ...
Fludarabine refractoriness (FR) represents an unsolved clinical problem of chronic lymphocytic leukemia (CLL) management. Although next-generation sequencing studies have led to the identification of a number of genes frequently mutated in FR-CLL, a comprehensive evaluation of the FR-CLL genome has not been reported. Toward this end, we studied 10 FR-CLLs by combining whole-exome sequencing and...
The purpose of the present study was to determine the nature of the photoreceptor that controls the light-dependent development of the peanut ovule and embryo, and to determine whether this photoreceptor activity is located in the ovular or the embryonic tissue. Peanut ovules were aseptically excised from surface sterilized gynophores (pegs) and cultured in darkness, continuous far red (FR), or...
OBJECTIVES/HYPOTHESIS Folate receptor (FR) expression, although known to be elevated in many types of cancer and inflammatory cells, has not been well characterized in head and neck squamous cell carcinoma (HNSCC). We hypothesized that tumor infiltrating inflammatory cells expressing FR-β could allow fluorescent visualization of HNSCC tumors using folate conjugated dyes even when FR expression ...
One of the important issues in hydraulic engineering is inspection of local scour depth around bridge pier. Using piles is one of the ways for confronting local scour and erosion. In this study, the experiments were conducted in an 8m long, 0.5m deep and 0.25m wide flume. And the effectof using piles and number of them observed on the amount of scour in three different Frude numbers. The shape ...
